[Tagging] Are there really substations that cannot be mapped as nodes?

Well, then people claim that "it is forbidden to map XYZ as node".

Maybe there would be benefit from extra state there, "discouraged"?
That could go on on landuse=cemetery nodes and so on.
(note: I am not planning to work on this)

Many people edit in poorly mapped parts of world, OSM Wiki should be
documenting OSM, not just well mapped OSM parts

many objects are not mappable as nodes at all

I just edited wiki to fix this

Right now it is not defining as preferred.

It is not even banning use of [power=substation] (without extra tags, or with
some substation=* values) on nodes.

https://wiki.openstreetmap.org/wiki/Proposed_features/Substation_nodes_extension#Vote
misleadingly claims that it is already banned.

I see that it also claims that utility=power is mandatory on building=service housing
substations (it is not, I mapped many building=service without adding this and it is fine,
especially if I added power=substation then adding utility=power adds no real benefit)Describing it as mandatory is again pretending that consensus already exists.
